Today I pulled out my Milwaukee Sawzall and Inventables foam aluminum. (I hacksawed the first ring with foam aluminum). I got a piece of the small cell stuff. It works well with double-cut mill bastards and 3M unitized wheels for finishing. Other tools are challenged by the material.
I’m going to look into anodizing one, and will also try the large cell sheet. Sizing is tricky too. This started out as a size 11 before it became a pinky ring.
